June Lockhart, who passed away at the remarkable age of 100, started her career in films, but achieved fame after moving almost exclusively to television. Having been given limited chances to shine in movies from her first appearance as a child in 1938 until 1947, she thrived on television in many beloved series, especially in Lassie.
Her Iconic Role in Lassie
Stepping in from a previous star in 1958, Lockhart remained in the series until 1964. Her role was Ruth Martin, married to agriculturalist Paul Martin and the foster mother of young Timmy Martin, whose collie was the titular hero of the series.
Even with playing a housewife, Lockhart skillfully avoided being outshone by the brilliant animal star. She described the program as “a fantasy about people on a rural property in which the canine solves all the problems in 22 minutes, in time for the last commercial”. After she left the series, Lockhart commented: “In six sexless years of playing a rural spouse and parent, I was rarely allowed to peck my on-screen husband on the cheek.”
Adventure into Lost in Space
Lockhart went straight into another successful series, Lost in Space (1965-68), a semi-spoof science fiction series targeted mostly at children and based by The Swiss Family Robinson. Lockhart and another actor played Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time deftly trying to survive visual effects. As the series continued, the narrative became less and less about this space family and increasingly about the boy and his friendship with a robot, and the timid antagonist Dr Zachary Smith.
Beginnings in Show Business
Lockhart’s feature film debut, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As British-born Kathleen and Canadian-born Gene were both actors in many of films, as well as on theater, it was almost certain that June, who was born in New York, would enter show business.
Her first stage appearance, at the tender age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).
Cinema Career
When her parent was given a deal by a film studio, after his success on Broadway, she moved with her parents to Hollywood, where Gene made around 300 films. After going to school in Beverly Hills, June started her career in movies, mainly in small roles in acclaimed pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the last one, she is charming as a New Yorker at a household party, whose dance card is arranged maliciously to stop Lockhart interacting with her brother.
More importantly, although she did not know it at the time, was Son of Lassie (1945). It was one of several sequels to the extremely successful Lassie Come Home (1943), in which another actress had played the female character who helps the canine to return to the family. In the subsequent film, Lockhart played the now grown-up character.
The affectionate way in which she interacted with both Lassie and her offspring, Laddie, hero of a wartime adventure in Nazi-occupied Norway, was in the consideration of the producers when it came to casting the Lassie TV series 13 years later.
Transition to Television and Broadway Achievement
Although she was given leading roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her film career was getting her nowhere and that television would be the solution. Before going in a different direction, she won acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as most promising newcomer.
A further significant run came with Petticoat Junction (1968-70), set in a country hotel, where Lockhart is a doctor and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic schedule persisted for the next five decades, with a regular role in General Hospital between 1984 and 1998. Among her many one-off appearances were as herself in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.
Later Career and Legacy
Her last TV appearance came in 2021 as the voice of Alpha Control in an episode of a digital platform’s new version of Lost in Space. In the big screen version starring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an influence the original series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a unpaid spokesperson brought her its Exceptional Public Achievement Medal.
Among her limited later feature films was the fantasy, Troll (1986) in which she played a witch, with her own daughter, Anne Lockhart, playing her younger self.
Personal Information
In 1951 she married John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her second marriage, to John Lindsay, an architect.
She is survived by her children and four grandchildren.
